linux-acpi-2.6/test on Thinkpad T61: Battery Absent

Hi,

I just pulled linux-acpi-2.6/test on my git tree, and rebuild the kernel, and now it doesn't detect any battery:

ACPI: Battery Slot [BAT0] (battery absent)

My tree is at faca89759dd7d4d87309f56cd09ae885a296fb4c and I'll try to bisect.

Cheers,

Can the battery be detected on the upstream kernel of 2.6.27-rc6? Please attach the output of acpidump, lspci -vxxx and dmesg.(Both dmesg on acpi_test git tree and 2.6.27-rc6 are needed).
Thanks.

Ok, it seems my mail didn't reach the list. In case it was because of attachments, I resend it.

Yes.

Ok, files are there: http://molly.corsac.net/~corsac/acpi/

Thanks for any help.

Ok, playing with git bisect, it seems the offending commit is:

50c0f43ff1199bbea5f0418d40df32f4d4029b13 is first bad commit commit 50c0f43ff1199bbea5f0418d40df32f4d4029b13

ACPI: EC: do transaction from interrupt context

From: Alexey Starikovskiy <[email protected]>

It is easier and faster to do transaction directly from interrupt
context
rather than waking control thread.
Also, cleaner GPE storm avoidance is implemented.

AK: Merged with earlier io port patch

Not sure exactly what the problem is, though.
